The present invention relates to a machine (1) for aligning, positioning and squaring sleepers. Positioning and squaring means comprise a table (5) that can slide vertically and on which two pairs of longitudinal bars (61, 62; 63, 64) are fastened, said bars being equipped with pushers (7) that protrude vertically downward, and means for longitudinally moving said bars in opposite directions such that, when the table (5) is in a lower position, the pushers (7) push the side faces of the sleepers (T) to position and square them. Aligning means comprise two aligning frames (81, 82) attached to the table (5) and equipped with longitudinal alignment bars (9), and means for transversally moving the frames (81, 82), such that, when the table (5) is in a lower position, the bar (9) pushes the sleepers (T) in a transverse direction to align them. The invention further relates to a method for operating the machine (1).

Abstract
The railway axle comprises railway wheels (1) mounted on an axle (2) by means of sliding adjustment, by virtue of the interposition of adjusted bushings (3) that are lubricated by means of grease on the inside (4) of the wheel (1), allowing the transition from one width to another without the need to release the wheel load. The wheels (1) are immobilized on the axle (2) in terms of the axle movement thereof by means of the sleeve (5) of claws (5') secured in rotation to the axle (2), the claws (5') being housed in annular, trapezoidal grooves (6') provided in rings (6) mounted on the hub (7) of the wheel (1), locking and unlocking involving a clamping sleeve (10) and pretensioned springs (11), the force of which may be overcome by a disc-like pusher (12), the railway axle furthermore including articulated compasses (13) connected by one end to a supporting sleeve (14) of the actual articulated compasses (13) and by the other end to a base ring (9) that is hooped and secured to the axle.
